Feedthrough（中文名字：真空连接器、真空接插件、穿墙子等）是一种可以穿过真空腔壁，在大气与真空间进行直流、射频（微波）功率和信号传输的密封装置。真空连接器广泛应用在科学研究、半导体制造、航天航空、光学设备、化学工业和医疗设备等多种领域。

       安德信科技联合研制生产的高性能多针及同轴真空连接器，经过超高真空、超高温、极限低温、高气压、高电压、高电流、微波性能等一系列测试，产品插入损耗低，性能稳定，质量过硬，可以适用于多种环境，已服务于数百家科研单位与企业。

       Feedthrough is a sealed device that can pass through the walls of a vacuum chamber and transmit direct current, radio frequency (microwave) power, and signals in the atmosphere and vacuum. Feedthrough are widely used in various fields such as scientific research, semiconductor manufacturing, aerospace, optical equipment, chemical industry, and medical equipment.

       The high-performance multipin and coaxial vacuum connector jointly developed and produced by ANDESUN Technology has undergone a series of tests including ultra-high vacuum, ultra-high temperature, extreme low temperature, high pressure, high voltage, high current, microwave performance, etc. The products have low insertion loss, stable performance, and excellent quality, and can be used in various environments.

       2021年5月26日，中国工信部组织专家对安德信科技的Feedthrough进行了成果评价，专家组一致认为为：该项目产品具有自主知识产权，打破了国外技术垄断，填补了国内空白，解决了“卡脖子”技术。该项目整体技术达到了国际先进水平，其中带宽技术指标达到了国际领先水平。
